And such sensitive data needs to be protected from prying eyes.

So how can we protect this data? Here is the Solution.

Android features a number of cool apps that let you lock apps through a password, PIN, fingerprint scanner or some really unique ways.

Some devices come with built-in app locker, but those whose device don’t have a default applocker they don’t need to worry.

Here in this article we have curated 25 Best App lockers that you can safely use in 2021.

Most of these apps are available on Google Play Store. Hence you can trust them and install on your device.

So let’s get in to the topic.

1. Norton App Lock

There aren’t a lot of options here but you can protect it from uninstallation by giving it admin privileges. There are also options to set a recovery email, along with a sneak peak feature that captures photos of intruders who enter the wrong PIN or pattern 3 times.

2. FingerSecurity

Wrapping our list is FingerSecurity, an Android app lock that is regarded as one of the top contenders among its type of service.

This app has a wide range of features that will otherwise not compromise the data on the phone. It also boasts an advanced feature that prevents unauthorized behaviors like installing apps.

The extent of our negative review for this app is on its scope; the free version is very limited forcing anyone to purchase the premium version for a very cheap price.

3. Privacy Knight

Privacy Knight is of one the best app lock for Android that covers some excellent features to secure your apps. It is ad-free and does not contain any in-app purchases.

The app gives you different methods to lock your apps.

You can use a PIN/pattern, fingerprint scanner, face tracking, or a Disguise cover, such as to blow, shake, or use a crash message to unlock.

You can hide private photos and videos, prevent uninstallation of the apps, hide notification previews from apps, etc.

It can also capture a picture of anyone who types the wrong password. Although not as popular as other app locks for Android, it has almost all the essential features.

4. Apex Launcher

Apex Launcher is an excellent launcher and it just so happens to have an applock function.

The launcher features are pretty good and include various customizations, icon pack support, various effects, and you can hide elements like the status bar or the dock if you want them invisible.

There are also some app security features as well, including the ability to hide apps from the app drawer and an applock function with a password protect layer for extra security.

It’s always a little better if it’s baked into the launcher than from a dedicated app, so if you don’t mind re-doing your home screens, this one and Smart Launcher 5 (listed below) are good alternatives to dedicated applock apps.

5. Smart Launcher 5

Smart Launcher has long been a favorite for the best Android launcher, with its simple “flower” favorites grid and sorted app folder.

The latest version, Smart Launcher 5, adds a ton of features and refinements.

Smart Launcher’s flower grid is still available, but it’s joined by a number of other well thought-out layouts designed to keep your favorite apps within easy reach of one hand, while smart search and an intelligently sorted and customizable app drawer makes it easy to find whatever you need, whether on your phone or out in the web.

Adaptive icons and colors, fully resizable widgets, and more customizations round out the package, making for a great update to a classic launcher.

You’ll need to shell out $7 for the Pro version of Smart Launcher to access the many of those extra features, including pop-up widgets and expanded gesture controls.

6. MaxLock

MaxLock is an awesome app locker for rooted Android devices only. That’s sad but if you have a rooted Android device, you get some great features with MaxLock.

The app is based on Xposed Framework, so you obviously need to have Xposed installed on your device. MaxLock is a totally free and ad-free app that unlike many app lockers out there, gives performance and battery the priority.

The locking methods include fingerprint, PIN, pattern and knock code. The open-source app includes ton of customization options, fake crash feature, a MasterSwitch to disable it easily, ability to remove thumbnail of apps in the recents window, and more.

The app is available in 30 different languages, and you can also upgrade to the premium version to remove ads.

However, the free version covers all the necessary features, and the number of ads in the app is very less.

8. Perfect AppLock

Perfect AppLock is another one of the better applocks out there.

It features the basics, including support for locking up WiFi, Bluetooth, and other toggles. It’s also rather frustrating to get passed.

It throws fake errors and all kinds of other messages out there. That makes people think there’s a different issue other than an applock. The free and paid versions provide the exact same features.

The only difference is that the paid version doesn’t have advertising. It’s a solid all around option, even if it’s name kind of oversells its capabilities a little bit.

9. Ultra AppLock

Ultra AppLock is a decent Android app lock that lets you do the basics. The app requires users to provide a password or a fingerprint biometric to access the app or files that have been locked.

It will send the owner of the phone a break-in alert if anyone tries to gain access and provided the wrong password. It comes with a built-in cleaner and battery saver features that would sometimes fail to work.

Ultra AppLock works seamlessly and will continue to do so as long as you veer away from trying to access the cleaner feature.

11. App Locker: Fingerprint & Pin (by KewlApps)

App Locker is one of the many app lockers for Android with the “app locker” moniker. The app isn’t very popular and it’s not hard to understand why.

It has a pretty outdated UI but if you look past that, it has some really unique features. Apart from the usual app locking features, App Locker lets you set custom lock settings on a per app basis.

So, you can set the primary lock method for an app to fingerprint, while pattern as the primary method for another app. Other than that, the app lets you choose a crash cover, set app re-lock delay and more. It includes ads but you can remove the ads by purchasing the full version of the app.

12. AppLock – Fingerprint Password (TOH Talent Team)

AppLock—Fingerprint Password offers an ideal app lock interface wherein a locked app or phone can only be accessed using a fingerprint sensor.

However, users do have other options to unlock the app by using a PIN or pattern for a password. Some Android users have reviewed the app as being useful and easy to use.

It has the ability to lock system apps and downloaded apps like Facebook, Whatsapp, Gallery, Messenger, Snapchat, and Instagram among others. This app lock app is, again, one of those apps that are not five-star quality but delivers what it claims.

The Keepsafe App Lock app is the simplest app locker in this list. The app features a gorgeous Material Design UI and packs in support for PIN, pattern and fingerprints.

There are options to set delay on when the apps are re-locked, prevent uninstall and hide PIN touches. If you’d like to disable the app temporarily, the app lets you disable it for a few hours.

The app is available in a free version but it features ads, however, you can make an in-app purchase to remove ads in the app. That pretty much sums up the app, I have used the app for quite a while and it’s as simple as it gets and works well.

15. App Lock (by Lucky Mobile Apps)

This app’s claim to fame is what separates it from others; it boasts that it can lock apps and keep unauthorized access at bay with a ‘secure’ but ‘easy to unlock’ pattern.

That means, even if you are one who easily forgets patterns and passwords, you won’t have to worry if you are using App Lock by Lucky Mobile Apps. It has the ability to lock both system apps and social apps.

On top of that, it is also powerful in locking Android Pay, Samsung Pay, Paypal, and so on. However, some users reported that a glitch is causing the app to drop when it comes to popularity so if developers can address that, then this app is going to give its competitors good competition.

If you don’t have a high-end phone, you can use this phone to make it more secure.

17. Smart AppLock (by ThinkYeah Mobile)

Smart AppLock is my second pick in this list for the best app locker for Android and there are two primary reasons for that. Firstly, it’s very lightweight and does not bring any kind of ads whatsoever.
Not on the lock screen or inside the app. Secondly, the app is fully updated and compatible with on-screen fingerprint sensors.

It basically means that the developer behind the app updates the app regularly to make it compliant with the newer Android APIs and devices.

If you are wondering if this app locker blurs the app preview in the recent menu then sadly, it doesn’t do that due to system restrictions and that is acceptable. As for the app, it’s fairly clean and does not bring any bloatware.

You can set a screen lock pattern or simply use your native fingerprint sensor that is already stored on your smartphone. Having said that, I did notice a persistent notification on the top, but you can disable it in one tap so that’s fine.

Simply put, if you want a simple and lightweight app locker for your Android smartphone, do take a look at Smart AppLock.

20. LOCX App Lock

LOCX App Lock is considered one of the bests vault and app lock apps for Android users. The app has a reputation for performing well in terms of locking private photos, secret videos, and text messages among others.

The app’s lock protection feature gives Android users all-around protection and will keep any Android mobile device out of unauthorized access.

Similar to other apps, access to locked apps and files is granted after providing a password or by biometric sensors.

Perhaps the best feature of this app is securing and encrypting private photos and files behind a master password.

22. AppLock – Fingerprint & Password (by SailingLab)

App Lock by SailingLab is one of those app lockers that has a multitude of features apart from protecting apps from unauthorized users.

While you have all the standard app locker features like PIN, Fingerprint and Pattern protection, it also brings photo vault, intruder selfie to catch people who are trying to break in and message security for hiding chat notifications from sensitive apps.

And that is not all, it also has a privacy browser but I would not really recommend using it.

From the face of it, AppLock is a feature-packed app locker and does a good job of protecting your chats and sensitive apps from prying eyes. Not to mention, there are themes as well for lock screen so there is that.

However, you would encounter some ads on the lock screen and that gets annoying sometimes.

App Lock by Smart Mobile is a fairly new app locker in the Play Store but it has gained a lot of traction due to its clean interface and straightforward approach.

Similar to other app lockers in the list, it lets you lock apps through fingerprint, PIN or pattern as you prefer.

There is a unique feature as well called profiles which categorize the apps in general, sensitive, social and payments labels.

You can, in fact, create your own profile and include apps of your choice. The benefit of profile is that you can enforce a set of rules in just one tap.

For example, you can unlock all the social apps in one tap once you are at home– no more fiddling with lock permissions of each and every app.

Other than that, you can set the apps as an Administrator too so that no one can uninstall it. However, I would not really recommend that as it’s a system-level privilege.
